Question

I used $.getJSON to retrieve the data from my database. If the parameter dID is not null, then there is one parameter like :

$.getJSON(urlGetProByDep, { depID: dID }, function (data) {
   //blah blah blah                    
});

But if both dID and cID are not null so the function will use 2 parameter as below :

 $.getJSON(urlGetProByDep, { depID : dID,catID : cID }, function (data) {
   //blah blah blah                    
 });

Could anyone tell me how can I change the paramter in {….} due to the value of dID and cID.

Thanks so much.

Answer 1

var data = {};
if(dID) {
    data.depID = dID;
}
if(cID) {
    data.catID = cID;
}

$.getJSON(urlGetProByDep, data, function (data) {
   //blah blah blah                    
});
